Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hello
I inherited a water damaged Samsung NC10. A glass of water was spilled on the keyboard.
I have dried the system out and it is now booting without issues. My only problem is that the keyboard has one key (P) that will not work at all. Every other key is fine. I removed the keyboard and reseated the connector ribbon but this has had no positive effect.
I plugged a USB keyboard in and (P) works.
Do you think that this means that the original keyboard is dead and should be replaced to have a fully functioning NC10? Or is it possible that water damage has made it so that no matter how many NC10 keyboards I plug in, it will have the same problem?
Thanks in advance.

usually when the keyboard's electronics are damaged, you get entire rows of keys (or sets) to fail, not individual ones. The behavior suggests this is not an electronic issue but a hard(hard)ware problem, as in no conductance of electrons. Have you taken the keyboard apart as far as possible and taken a look at the surface underneith the "P"? Perhaps there is water trapped there or something has slided out of place?
